OF I DALLAS, TEXAS coNcnETn-BnIcK-MoLm tG DEVICE Application filed. May17,

This invention relates to concrete brick molding machines, and refersmore particularly to such a machine adapted to allow the facing of anumber of brick, and then the lifting of the brick from the molding orseparation plates by the actuation of a ratchet lever controlling a pairof eccentrics journaled on a common shaft, each eccentricalfectingdifferent parts of the machine to accomplish the results abovementioned in the order named.

The object of this invention is the provision of a device which willperform the above in a fraction of the time now taken by the employmentof devices now in common use, and further, the elimination of excessivemanual handling of each brick.

By the use of this machine, the molds, being fixed in alignment,mechanical attachments for filling the molds and removing the brick, maybe attached or used in co-operation with the device, and the manualhandling of the brick entirely eliminated.

Therefore, it will be readily seen and understood that time, labor, andmoney may be saved and a more perfect brick be produced in greaterquantities than has beendone in common practice heretofore.

Now, I wish to make clear that this machine is adapted to be employed inthe manufacture of poured concrete brick (not dry tamped) and for noother type of brick, but of course may be made in sizes to accom1nodateconcrete blocks or other concrete products of greater size than brick.

The device may be better understood in the course of the followingdetailed description, of which the annexed drawings form a part, and inwhich Figure 1 is an. end elevation of the machine embodying myinvention Figure 2 is a side elevation, andF gure 3 is a top or planview.

Continuing the description, the machine is provided with legs 11 ofchannel iron, set on a concrete base 2, and with bracing cross members3--3, above the base. Joining the leg members at the top of the machineare members 4:4c, which serve as a part of the brick forms and areprovided with grooves adapted to receive the separation 1928.: Serialno. 278,469.

plates 19 therein and serve as guides for them during the operation ofthe machine. A shaft 5 is journaled in bearings 5 which are secured onmembers 3 -8. Upon this shaft are supported eccentrics 77 and 88, whichare arranged in the frame of the ma chine below the molds. Theseeccentrics are secured to the shaft by means of pins 7 a and 8* At oradjacent one end of the shaft is rigidly secured a ratchet wheel- 6, andadi jacent the wheel is pivotally secured a ratchet lever 9having aspring controlled ratchet 10 operated into or out of engagement with theratchet wheel by means of handle 9. Alined above each eccentric arerollers 13'-13 and -'25, which each are secured to different elements ofthe mold now described. Rollers 13-13 are pivotally journalled at 14 inthe bottom of members 15. The latter are guided in vertical freedom ofmovement by guide members 11-11 and 11"-11 These members 15 are securedto and support channel as bases, the bricks are adapted to be formed.

Steam pipes to generate heat (26) are supported on cross members 11,which aid in equalization of temperature within the machine. 1

In operation, the ratchet is actuated to allow the rollers to be in thelowest possible position on the eccentrics just opposite the positionshown in the drawings. This lowers the brick supporting elements so thatthe tops thereof are alined slightly above the i bottoms ,of members1-4. This. forms a space the required depth of the brick to be poured.The tops of the separation plates are in a position alined slightlybelow the tops of the members le-4; After the bricks are poured and thetops faced and attain a natural set, the ratchet is operated to elevatethe roller riding on the eccentric 7, to move all the moving parts ofthe molds upward for a space of about four and one half inches to allowthe brick to be faced on the ends. After this is accomplished, bycontinuing the rotation of the shaft 5 separation plates are caught by ashoulder formed upon them coming against the lower edge of members 44and their motion is stopped. Then eccentric 8 comes in contact withroller 25 and raises the bottom of the form and brick to an elevationabove the plates, allowing them to be mechanically removed by a suitableattachment not forming part of this invention.

What I claim is:

1. In a device of the character described, a frame, a shaft carried bythe frame, a ratchet adapted to rotate the shaft, a plurality ofeccentrics journaled on said shaft and adapted to be rotated with theshaft, rollers adapted to ride on the outer periphery of saideccentrics, part of said rollers journaled in members in rigidattachment to a series of brick supporting members, and the balance ofsaid rollers journaled in members in rigid attachment to brickseparation members, adapted to operate vertically between the bricksupporting members, and rigid members secured to the top of the frameadapted to guide the plates and with adjacent plates to form the foursides of each brick form.

2. A brick molding device comprising a frame, a ratchet rotated shaftjournaled therein, and having secured thereon a plurality of eccentrics,rollers adapted to ride said eccentrics, part of said rollers adapted tohave supported therefrom brick separation plates, the balance of saidrollers being adapted to support brick supporting members, guides todirect the movement of the brick supporting members vertically, groovedmembers of the frame to guide the movement of the plate members, andform part of the wall structure wherein the bricks are molded, and meanson the plates adapted to engage the grooved members to limit themovement of the plate members.

3. A brick molding machine comprising a frame, a shaft journaledtherein, a ratchet mechanism adapted to rotate said shaft, a pluralityof eccentrics in attachment to the shaft, rollers adapted to rideeccentrics, part of said rollers being journaled in members supportingbrick separation plates, the balance of said rollers being j ournaled inmembers supporting a plurality of brick supportm members, guides adaptedto limit the CHARLES M. BEALS.

movement of said supporting members to a vertical plane, and members atthe top of the frame to guide the plate members and with such adjacentmembers to form the walls wherein each brick is molded.
